Get the following:

• 9 LumiNet nodes in 3x3 grid with cables

• 1 vector node (marked) with cable

• 1 battery

• 1 Arduino board (for serial link)

• Arduino LumiNet Edition software

• from USB stick, DVD, or luminet.cc

Blink for LumiNet

• Mac: Get Info on Arduino for LumiNet app, check 32bit option

• Launch Arduino for LumiNet

• Select board: “LumiNet Vector Node”

• Select your serial port

• Open Sketchbook: Examples: Digital: Blink

• Upload sketch as usual


Jan Borchers

Programming by Infection

• Disconnect vector from Arduino

• Remove jumper cable from vector

• Connect vector to LumiNet network

• Connect battery to any Vcc+GND pins

• Power up LumiNet

• Watch infection spread (~ 1 minute)

• When all nodes are blue or green, power off


Jan Borchers

Run LumiNet Blink

• Remove vector

• Power on

• All nodes should blink

• Congratulations!

Experiment #2: LightRing• Power net off and remove vector

• Put vector jumper cable back

• Connect vector to Arduino again


Jan Borchers

Install LightRing code on LumiNet

• Load LightRing code from file(came with IDE)

• Upload to vector

• Remove jumper cable from vector

• Move vector from Arduino back to net

• Power up net to infect it (takes a while)

• Power down net, remove vector, power up


Jan Borchers

Using LightRing

• Ground any RX pin (e.g., pin 7) with a jumper cable for light ripple effects

• How does LightRing work?

• Buffers incoming signal on all 4 sides, passes it on after 100ms to opposite side and immediately to the other 2 sides

• Simple code, emergent behavior


Jan Borchers

Experiment #3:Social LightRing

• Connect IR sender/receiver node to any node

• Remember to connect only

• WEST to EAST or

• NORTH to SOUTH!

• To orient boards correctly,let jumper point to upper left corner

• Pass light ripples from net to net or jacket!Sunday, July 19, 2009
